[PATCH 2/3] perf test: Add pmu-events test for aliases with hyphens

From: John Garry
Date: Mon Jan 17 2022 - 10:15:55 EST


Add a test for aliases with hyphens in the name to ensure that the
pmu-events tables are as expects. There should be no reason why these sort
of aliases would be treated differently, but no harm in checking.
